keep or destroy?

I have no idea how this guy got into my tank (as I have no corals yet).
Did I score or is this going to be trouble?
Thanks all.

Remove it. It's a Tritoniopsis.

@Lionfish Lair
I have a hundred of these tiny white things in the overflow and tank.
Are they larva from the Tritoniopsis?
Thank you.

Those are not anything to worry about, but i would wonder what the eggs were from in the first pic. Maybe lionfish will know

You mean the other white blobs? I don't think they're anything much. Whatever is it, is doesn't belong to the nudi, as they lay eggs in a thick ribbon set on its edge.

As said of the other white blobs, they are nothing to worry about, as they are pineapple sponges.

i can't speak from experience and i may be mistaken on the first group of photos but they look like a species of nudibranch. i would investigate further to determine if they're a pest or harmless.
as for these guys they're just pineapple sponges and are a benefit to your system as they're filter feeders that add biodiversity. chances are if your system is new they'll balance themselves out once thing mature a little. the same can be said for many problems or what people perceive to be problems.
